TECHNICAL FIELD

The present disclosure is directed to novel retinoic acid receptor-related orphan receptor gamma (“RORγ” or “ROR-gamma”) modulators, processes for their preparation, pharmaceutical compositions containing these modulators, and their use in the treatment of inflammatory, metabolic, autoimmune and other diseases mediated by RORγ.

BACKGROUND

Retinoic acid receptor-related orphan receptors (RORs) are a subfamily of transcription factors in the steroid hormone nuclear receptor superfamily (Jetten & Joo (2006) Adv. Dev. Biol. 2006, 16, 313-355). The ROR family consists of ROR alpha (RORα), ROR beta (RORβ) and ROR gamma (RORγ), each encoded by a separate gene (in human: RORA, RORB and RORC, respectively; in mouse: rora, rorb and rorc, respectively). RORs contain four principal domains shared by the majority of nuclear receptors: an N-terminal domain, a highly conserved DNA-binding domain (DBD) consisting of two zinc finger motifs, a hinge domain, and a ligand binding domain (LBD). Each ROR gene generates several isoforms, differing only in their N-terminal domains. RORγ has two isoforms: RORγ1 and RORγ2 (also known as RORγt). RORγ refers to RORγ1 and/or RORγt. RORγ1 is expressed in a variety of tissues including thymus, muscle, kidney and liver, but RORγt is exclusively expressed in the cells of the immune system, has a critical role in thymopoiesis and the development of several secondary lymphoid tissues, and is a key regulator of Thl7 cell differentiation (Jetten, 2009, Nucl. Recept. Signal., 7:e003, doi:10.1621/nrs.07003, Epub 2009 Apr. 3).

Thl7 cells are a subset of T helper cells which preferentially produce the pro-inflammatory cytokines IL-17A, IL-17F, IL-21 and IL-22. Thl7 cells and their effector molecules, such as IL-17, IL-21, IL-22, GM-CSF and CCL20, are associated with the pathogenesis of several autoimmune and inflammatory diseases, such as rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, psoriasis, inflammatory bowel disease, allergy and asthma (Maddur et al., 2012, Am. J. Pathol., 181:8-18). Recent findings support a role for IL17 and Thl7 cells in the pathogenesis of acne (Thiboutot et al., 2014, J. Invest. Dermatol., 134(2):307-10, doi: 10.1038/jid.2013.400; Agaketal., 2014, J. Invest. Dermatol., 134(2):366-73, doi: 10.1038/jid.2013.334, Epub 2013 Aug. 7). Thl7 cells are also potent inducers of inflammation associated with endometriosis, a chronic inflammatory disease (Hirata et al., 2010, Endocrinol., 151:5468-5476; Hirata et al., 2011, Fertil Steril., July; 96(1):113-7, doi: 10.1016/j.fertnstert.2011.04.060, Epub 2011 May 20). Additionally, Thl7 cells have a key role in the mouse autoimmune models of experimental autoimmune encephalomyelitis (EAE), collagen-induced arthritis (CIA) and adjuvant-induced arthritis (AIA) (Bedoya et al., 2013, Clin. Dev. Immunol., 2013:986789. Epub 2013 Dec. 26. Thl7 cells are activated during inflammatory and autoimmune disease processes and are responsible for recruiting other inflammatory cell types, particularly neutrophils, to mediate pathology in target tissues (Miossec & Kolls, 2012, Nature Rev., 11:763-776; Korn et al., 2009, Annu. Rev. Immunol., 27:485-517). Aberrant Thl7 cell function has been implicated in a variety of autoimmune diseases, including multiple sclerosis and rheumatoid arthritis. Autoimmune disease is believed to arise from the disruption of the equilibrium between effector and regulatory T cells (Solt et al., 2012, ACS Chem. Biol., 7:1515-1519, Epub 2012 Jul. 9). The importance of RORγt to Thl7 cell differentiation and the pathogenic role of Thl7 cells is evidenced by the fact that RORγt-deficient mice have very few Thl7 cells and have a reduction in severity of EAE (Ivanov et al., 2006, Cell, 126:1121-1133).

Recently, IL-17-producing neutrophils have been identified as promoting inflammation leading to both microbial clearance and IL-17-associated tissue damage in the cornea and other tissues (Taylor et al., 2014, J. Immunol, 192:3319-3327; Taylor et al., 2014, Nat. Immunol., 15:143-151), supporting a role for compounds that inhibit RORγ activity in the treatment of corneal ulcers and other diseases and disorders associated with IL-17 expressing neutrophils.

Circadian rhythms are daily cycles of behavioral and physiological changes that are regulated by endogenous circadian clocks. A number of studies have established links between nuclear receptor (including RORγ) function and expression, the circadian regulatory circuitry, and the regulation of various physiological processes (Jetten (2009) op. cit.).

Obstructive sleep apnea syndrome (OSAS) is a chronic inflammatory disease regulated by T lymphocytes. OSAS patients have a significant increase in peripheral Thl7 cell frequency, IL-17 and RORγt levels (Ye et al., 2012, Mediators Inflamm., 815308, doi: 10.1155/2012/815308, Epub 2012 Dec. 31).

A number of studies have provided evidence of a role of RORs in cancer. Mice deficient in the expression of RORγ exhibit a high incidence of thymic lymphomas that metastasize frequently to liver and spleen. High expression of Thl7-associated genes (including RORγ) and high levels of Thl7 cells in the tumor microenvironment has been shown to correlate with a poor prognosis in various cancers, including lung, gastric, breast and colon cancer (Tosolini et al., 2011, Cancer Res., 71:1263-1271, doi: 10.1158/0008-5472.CAN-10-2907, Epub 2011 Feb. 8; Su et al., 2014, Immunol. Res., 58:118-124, doi: 10.1007/s12026-013-8483-y, Epub 2014 Jan. 9; Carmi et al., 2011, J. Immunol., 186:3462-3471, doi: 10.4049/jimmunol.1002901, Epub 2011 Feb. 7; Chen et al., 2013, Histopathology, 63:225-233, doi: 10.1111/his.12156, Epub 2013 Jun. 6). Recent evidence also shows that RORγ is overexpressed and amplified in metastatic castration-resistant prostate cancer tumors, and that RORγ antagonists suppressed tumor growth in multiple androgen receptor-expressing xenograft prostate cancer models. See e.g., Nature Medicine, Mar. 28, 2016, advance online publication, doi: 10.1038/nm.4070.

RORγ has also been identified to have a regulatory role in lipid/glucose homeostasis, and has been implicated in metabolic syndrome, obesity (Meissburger et al., 2011, EMBO Mol. Med., 3:637-651), hepatosteatosis, insulin resistance and diabetes.

Further support for the role of RORγ in the pathogenesis of inflammatory, metabolic, circadian effect, cancer, and autoimmune diseases and disorders can be found in the following references: Chang et al., 2012, J. Exp. Pharmacol., 4:141-148; Jetten et al., 2013, Frontiers Endocrinol., 4:1-8; Huh & Littman, 2012, Eur. J. Immunol., 42:2232-2237; Martinez et al., 2008, Ann. N.Y. Acad. Sci., 1143:188-211; Pantelyushin et al., 2012, J. Clin. Invest., 122:2252-2256; Jetten & Ueda, 2002, Cell Death Differen., 9:1167-1171; Solt et al., 2010, Curr. Opin. Lipidol., 21:204-211.

In light of the role that RORγ plays in disease pathogenesis, inhibition of RORγ activity and Thl7 cell differentiation and activity, including IL17 production, is of significant therapeutic benefit. Compounds that inhibit RORγ activity and hence have utility in the treatment of e.g., inflammatory, autoimmune, metabolic, circadian effect, cancer, and other diseases mediated by RORγ are described in WO 2014/179564 and WO 2015/116904. However, there is a continuing need for the development of new and improved drugs that modulate RORγ and are useful in the treatment of disease.

Typically, the subject is a human in need of treatment.

Certain of the disclosed compounds may exist in various stereoisomeric forms. Stereoisomers are compounds that differ only in their spatial arrangement. Enantiomers are pairs of stereoisomers whose mirror images are not superimposable, most commonly because they contain an asymmetrically substituted carbon atom that acts as a chiral center. “Enantiomer” means one of a pair of molecules that are mirror images of each other and are not superimposable. Diastereomers are stereoisomers that contain two or more asymmetrically substituted carbon atoms. The symbol “*” in a structural formula represents the presence of a chiral carbon center. “R” and “S” represent the configuration of substituents around one or more chiral carbon atoms. Thus, “R*” and “S*” denote the relative configurations of substituents around one or more chiral carbon atoms.

As used herein, a hyphen (“-”) at the beginning or end of a recited group designates the point at which a recited group is attached to a defined group. For example, —SO₂—(C₁-C₃)alkyl-(C₂-C₆)cycloalkyl means that the group is attached via the sulfonyl.

“Racemate” or “racemic mixture” means a compound of equimolar quantities of two enantiomers, wherein such mixtures exhibit no optical activity, i.e., they do not rotate the plane of polarized light.

“Geometric isomer” means isomers that differ in the orientation of substituent atoms in relationship to a carbon-carbon double bond, to a cycloalkyl ring, or to a bridged bicyclic system. Atoms (other than H) on each side of a carbon-carbon double bond may be in an E (substituents are on opposite sides of the carbon-carbon double bond) or Z (substituents are oriented on the same side) configuration. “R^(c),” “S,” “S*,” “R*,” “E,” “Z,” “cis,” and “trans,” indicate configurations relative to the core molecule. When a disclosed compound is named or depicted by structure without indicating a particular geometric isomer form, it is to be understood that the name or structure encompasses one geometric isomer free of other geometric isomers, mixtures of geometric isomers, or mixtures of all geometric isomers.

The compounds of the herein may be prepared as individual enantiomers by either enantio-specific synthesis or resolved from an enantiomerically enriched mixture. Conventional resolution techniques include forming the salt of a free base of each isomer of an enantiomeric pair using an optically active acid (followed by fractional crystallization and regeneration of the free base), forming the salt of the acid form of each enantiomer of an enantiomeric pair using an optically active amine (followed by fractional crystallization and regeneration of the free acid), forming an ester or amide of each of the enantiomers of an enantiomeric pair using an optically pure acid, amine or alcohol (followed by chromatographic separation and removal of the chiral auxiliary), or resolving an enantiomeric mixture of either a starting material or a final product using various well known chromatographic methods.

When the stereochemistry of a disclosed compound is named or depicted by structure, the named or depicted stereoisomer is at least 60%, 70%, 80%, 90%, 99% or 99.9% by weight pure relative to all of the other stereoisomers. Percent by weight pure relative to all of the other stereoisomers is the ratio of the weight of one stereoisomer over the weight of the other stereoisomers. When a single enantiomer is named or depicted by structure, the depicted or named enantiomer is at least 60%, 70%, 80%, 90%, 99% or 99.9% by weight optically pure. Percent optical purity by weight is the ratio of the weight of the enantiomer over the weight of the enantiomer plus the weight of its optical isomer.

When the stereochemistry of a disclosed compound is named or depicted by structure, and the named or depicted structure encompasses more than one stereoisomer (e.g., as in a diastereomeric pair), it is to be understood that one of the encompassed stereoisomers or any mixture of the encompassed stereoisomers are included. It is to be further understood that the stereoisomeric purity of the named or depicted stereoisomer is at least 60%, 70%, 80%, 90%, 99% or 99.9% by weight pure relative to all of the other stereoisomers. The stereoisomeric purity in this case is determined by dividing the total weight in the mixture of the stereoisomers encompassed by the name or structure by the total weight in the mixture of all of the stereoisomers.

When a disclosed compound is named or depicted by structure without indicating the stereochemistry, and the compound has one chiral center, it is to be understood that the name or structure encompasses one enantiomer of compound free from the corresponding optical isomer, a racemic mixture of the compound, or mixtures enriched in one enantiomer relative to its corresponding optical isomer.

When a disclosed compound is named or depicted by structure without indicating the stereochemistry and e.g., the compound has more than one chiral center (e.g., at least two chiral centers), it is to be understood that the name or structure encompasses one stereoisomer free of other stereoisomers, mixtures of stereoisomers, or mixtures of stereoisomers in which one or more stereoisomers is enriched relative to the other stereoisomer(s). For example, the name or structure may encompass one stereoisomer free of other diastereomers, mixtures of stereoisomers, or mixtures of stereoisomers in which one or more diastereomers is enriched relative to the other diastereomer(s).

The compounds of the herein may be present in the form of pharmaceutically acceptable salts. For use in medicines, the salts of the compounds of the invention refer to non-toxic “pharmaceutically acceptable salts.” Pharmaceutically acceptable salt forms include pharmaceutically acceptable acidic/anionic or basic/cationic salts.

Pharmaceutically acceptable basic/cationic salts include, the sodium, potassium, calcium, magnesium, diethanolamine, n-methyl-D-glucamine, L-lysine, L-arginine, ammonium, ethanolamine, piperazine and triethanolamine salts.

Uses of Compounds and Pharmaceutically Acceptable Compositions

Compounds and compositions described herein are generally useful for modulating RORγ. Thus, in some embodiments, the present disclosure provides a method of treating inflammatory, metabolic and autoimmune diseases or disorders mediated by RORγ, comprising administering a provided compound or composition. More particularly, the compounds and compositions described herein act as inverse agonists or antagonists of RORγ.

As used herein, the terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment may be administered after one or more symptoms have developed, i.e., therapeutic treatment. In other embodiments, treatment may be administered in the absence of symptoms. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors), i.e., prophylactic treatment. Treatment may also be continued after symptoms have resolved, for example to prevent or delay their recurrence.

Modulation of RORγ (or to modulate RORγ), means that a change or alteration in the activity of RORγ has occurred from the administration of one or more of the compounds described herein. Modulation may be an upregulation (increase) or a downregulation (decrease) in the magnitude of the activity or function of RORγ. Exemplary activities and functions include e.g., binding characteristics, enzymatic activity, cell receptor activation, transcriptional activity, and signal transduction. In one aspect, the compounds described herein inhibit RORγ. In further aspects, the compounds described herein act as agonists, antagonists, or inverse agonists of RORγ.

EXEMPLIFICATION

As depicted in the Examples below, in certain exemplary embodiments, compounds are prepared according to the following general procedures. It will be appreciated that, although the general methods depict the synthesis of certain compounds herein, the following general methods, and other methods known to one of ordinary skill in the art, can be applied to all compounds and subclasses and species of each of these compounds, as described herein.

General Description of Synthesis

The compounds described herein can be readily prepared according to the following reaction schemes and examples, or modifications thereof, using readily available starting materials, reagents and conventional synthesis procedures. Many of the reactions can also be carried out under microwave (MW) conditions or using conventional heating or utilizing other technologies such as solid phase reagents/scavengers or flow chemistry. In these reactions, it is also possible to make use of variants which are themselves known to those of ordinary skill in the art, but are not mentioned in greater detail. Furthermore, other methods for preparing compounds described herein will be readily apparent to a person of ordinary skill in the art in light of the following reaction schemes and examples. In cases where synthetic intermediates and final products contain potentially reactive functional groups, for example amino, hydroxy, thiol and carboxylic acid groups, that may interfere with the desired reaction, it may be advantageous to employ protected forms of the intermediate. Methods for the selection, introduction and subsequent removal of protecting groups are well known to those skilled in the art. In the discussion below variables have the meanings indicated above unless otherwise indicated. The abbreviations used in these experimental details are listed below and additional ones should be known to a person skilled in the art of synthesis. In addition, one can refer to the following references for suitable methods of synthesis as described in March, Advanced Organic Chemistry, 3rd edition, John Wiley & Sons, 1985, Greene and Wuts, Protective Groups in Organic Synthesis, 2^(nd) edition, John Wiley & Sons, 1991, and Richard Larock, Comprehensive Organic Transformations, 4^(th) edition, VCH publishers Inc., 1989.

Generally, reagents in the reaction schemes are used in equimolar amounts; however, in certain cases it may be desirable to use an excess of one reagent to drive a reaction to completion. This is especially the case when the excess reagent can be readily removed by evaporation or extraction. Bases employed to neutralize HCl in reaction mixtures are generally used in slight to substantial excess (1.05-5 equivalents).

Where NMR data are presented, spectra were obtained on a Varian 400 (400 MHz) or 300 (300 MHz) and are reported as ppm downfield from tetramethylsilane with number of proton, multiplicities and coupling constants indicated parenthetically along with reference to deuterated solvent.

In a seventh process, a compound of Formula I is prepared from another compound of Formula I. Non-limiting examples of this process include: (1)Treatment of a compound of Formula I wherein R⁵ or R⁶ is OMe with BBr₃ or Me₃SiI to give a compound of Formula I wherein R⁵ or R⁶ is OH; (2) Reaction of a compound of Formula I wherein Cy¹ or Cy² is azetidinyl, pyrrolidinyl or piperidinyl bearing a free NH with an alkylating agent such as an (C₁-C₆)alkyl halide or halo(C₁-C₆)alkyl triflate to give a compound of Formula I, wherein R⁵ or R⁶ is (C₁-C₆)alkyl or halo(C₁-C₆)alkyl attached to the N of the azetidine, pyrrolidine or piperidine ring; (3) Reaction of a compound of Formula I wherein Cy¹ or Cy² is azetidinyl, pyrrolidinyl or piperidinyl bearing a free NH with an heteroaryl halide such as an optionally substituted 2-chloropyridine, 2-chloropyrimidine or 4-chloropyrimidine to give a compound of Formula I, wherein R⁵ or R⁶ is a heteroaryl group such as an optionally substituted pyridinyl or pyrimidinyl group attached to the N of the azetidine, pyrrolidine or piperidine ring; (4) Oxidation of compound of Formula I in which Cy¹ or Cy² is a pyridine ring with a peracid, such as m-CPBA, to the corresponding pyridine N-oxide of Formula I; (5) Reduction of a compound of Formula I, wherein R⁵, R⁶, R⁷ or R⁸ is —C(═O)OR^(e), or (C₁-C₂)alkyl substituted by —C(═O)OR^(c), with a hydride reducing agent such as NaBH₄, NaBH₄/CaCl₂ or LiBH₄ to give a compound of Formula I in which R⁵, R⁶, R⁷ or R⁸ is (C₁-C₃)alkyl substituted by OH; (6) Hydrolysis of a compound of Formula I, wherein R⁵, R⁶, R⁷ or R⁸ is —C(═O)OR^(e), or (C₁-C₃)alkyl substituted —C(═O)OR^(c) and R^(c) is (C₁-C₃)alkyl with an alkali metal hydroxide to provide a compound of Formula I, wherein R⁵, R⁶, R⁷ or R⁸ is —C(═O)OH, or (C₁-C₃)alkyl substituted —C(═O)OH; (7) Reaction of a compound of Formula I, wherein R⁵, R⁶, R⁷ or R⁸ is —C(═O)OH, or (C₁-C₃)alkyl substituted —C(═O)OH with an amine R^(d)R^(e)NH under peptide coupling conditions to give a compound of Formula I, wherein R⁵, R⁶, R⁷ or R⁸ is —C(═O)NR^(d)R^(e), or (C₁-C₃)alkyl substituted —C(═O)NR^(d)R^(e); (8) Oxidation of a compound of Formula I, in which Cy¹ and/or Cy² is substituted with R⁵ or R⁶ which is —SR^(b), with a peracid, such as m-CPBA, to give a compound of Formula I wherein R⁵ and/or R⁶ is —S(O)_(k)R^(b) in which k is 1 or 2.

An amine of Formula 155 and a halonitroester of Formula 160, wherein R¹¹⁰ is F or Cl, are reacted in the presence of an organic base, such as i-Pr₂NEt, to give a nitroaniline of Formula 165. The nitro group of 165 is reduced using, for example, zinc dust in the presence of NH₄C₁, iron powder in HOAc, SnCl₂, or H₂ in the presence of Pd on C, to give a diaminoester of Formula 170. Diaminoester 170 is converted to benzimidazole ester 175 using procedures described in the third process. Finally, the ester in 175 is hydrolyzed using an alkali metal hydroxide to give 100.

An amine 155 is reacted with a nitrobenzene 180, wherein R¹¹⁰ is F or C₁ to given a nitroaniline 185. Reduction of 185 using, for example, SnCl₂ gives diamine 190. Diamine 190 is converted to bromobenzimidazole 195 using procedures described in the third process. Bromobenzimidazole 195 is converted to aminobenzimidazole 110 using for example NaN₃, CuI.

In a tenth process, diamines of Formula 125, which are precursors to compounds of Formula I, are prepared in three steps. Reaction of benzoic acids of Formula 200 with amines of Formula 105 under peptide coupling conditions, mediated by for example HATU, HBTU or EDC, gives amides of Formula 205. Reaction of 205 with amine of Formula 155 gives nitroanilines of Formula 210 which are reduced using, for example, SnCl₂ to give diamines 125.

In an eleventh process, benzimidazoles of Formula 145, which are precursors of compounds of Formula I, are prepared in three steps. Diaminoester 215 is reacted with carboxylic acids of Formula 120, as described in the third process, to give benzimidazole esters of Formula 220. Treatment of esters 220 with alkali metal hydroxides gives acids of Formula 225 which are reacted with amines of Formula 105 under peptide coupling conditions, mediated by for example HATU, HBTU or EDC, to afford amides of Formula 145.

Biological Assays Radio-Ligand RORγ Binding Assay (Assay 1)

Compounds described herein were tested for ability to bind to RORγ in a cell-free competition assay with commercially available radio-ligand (RL), 25-hydroxy [26,27-³H]-cholesterol (PerkinElmer, Cat. #NET674250UC), for a ligand binding site on a recombinant RORγ Ligand Binding Domain (LBD) protein expressed as a 6×His-Glutathione-S-Transferase (GST) fusion. The assay was performed in 96-well SPA plates (PerkinElmer, Cat. #1450-401) in 50 mM HEPES buffer, pH 7.4, containing 150 mM NaCl, 5 mM MgCl₂, 10% (v/v) glycerol, 2 mM CHAPS, 0.5 mM β-octylglucopyranoside and 5 mM DTT. Tested compounds were dissolved in DMSO, and semi-log (3.162×) serial dilutions of the compounds were prepared in the same solvent. Two μL of the DMSO solutions were mixed with 28 μL of 8.6 nM 25-hydroxy [26,27-³H]-cholesterol and 50 μL of 24 nM RORγ LBD. The plate was shaken at 700 rpm for 20 min and incubated for 10 min at rt, after which 40 μL of poly-Lys YSi SPA beads (PerkinElmer, Cat. #RPNQ0010) were added to achieve 50 pg of the beads per well. The plate was incubated on an orbital shaker for 20 min and then for 10 min without agitation at rt. SPA signal for tritium beta radiation was registered on PerkinElmer Microbeta plate reader. Percent inhibition values were calculated based on the high signal obtained with DMSO control and the low signal observed with 10 μM standard RORγ inverse agonist T0901317 (SigmaAldrich, Cat. #T2320). The percent inhibition vs. concentration data were fit into a four-parameter model, and IC50 values were calculated from the fit as the concentrations corresponding to the inflection points on the dose-response curves. Inhibitory constants (Ki) were calculated using the following equation, where [RL] is the concentration in the assay and K_(D) is a dissociation constant of 25-hydroxy [26,27-³H]-cholesterol:

$K_{i} = {\frac{{IC}_{50}}{\left( {1 + \frac{\lbrack{RL}\rbrack}{K_{D}}} \right)}.}$

RORγt 5×RORE Assay in Jurkat Cells (Assay 2)

Compounds described herein were tested for RORγ inverse agonist activity in a cell-based, transcriptional activity assay. Secreted Nanoluc® luciferase was used as a reporter for transcriptional activity of the full-length RORγt in Jurkat cells (ATCC, Cat. #TIB-152). A reporter plasmid was constructed by inserting 5 repeats of the ROR Response Element (RORE) AAAGTAGGTCA (SEQ ID NO:1) into a commercially available promoterless plasmid pNL1.3[secNluc] (Promega, Cat. #N1021) using KpnI and HindIII restriction sites. The expression plasmid for RORγt was purchased (Geneocopoeia, Cat. #EX-T6988-M02). Jurkat cells (30 million cells) were transfected with 11 pg of EX-T6988-MO2 and 26 pg of the reporter plasmid in OptiMEM® media using Lipofectamine® LTX and Plus™ reagents (Life Technologies, Cat. #15338-100). After 5-6 hrs of incubation at 37° C./5% CO₂, the cells were collected, resuspended in phenol-red free RPMI media containing 10% (v/v) delipidated FBS (Hyclone, Cat. #SH30855.03) and dispensed into 96-well clear bottom tissue culture plates (CoStar, Cat. #3603), at 80,000 cells per well. Tested compounds were added to the cells in the same media (final concentration of DMSO was 0.1% (v/v)), and the plates were incubated at 37° C./5% CO₂ for 16-18 hrs. Luciferase activity in the conditioned supernatants was determined with NanoGlo® assay reagents (Promega, Cat. #N1130). Percent inhibition values were calculated based on the fully inhibited and non-inhibited (DMSO) controls, and the values were regressed against concentrations of the tested compounds to derive IC50 values using a four-parameter non-linear fitting model.

The results of assays 1 and 2 are shown in Table 3 below.
